We are having issues getting our murata (bcm4339) chip to work in simultaneous dual band. The chip supports it but iwlist returns 1.
The system is lunix kernel 4.2.7 running hostapd and the bcrmfmac driver with a TI ARMCore. Murata are no help at all.
Any help appreciated we have been battling with this now for a few months
Unfortunately the details you have provided are not enough to help you out. What is the that you are trying to do? Can you provide the details of the logs from the the point to insmoding the module to the point at which you are running into this issue.
Note that Murata or Cypress doesn't support mac yet. But fmac support is on Cypress roadmap and we shall try to help you out on a bets effort basis.
